Dependency Injection

[CaoAnhDev]

Hi, can I ask: why the constructor never be called?

@Injectable()
export class MessageHandler {
  constructor(
    // @Inject(SubscriptionService)
    // private subscriptionService: SubscriptionService,
    // @Inject(NotificationService)
    // private notificationService: NotificationService,
    private readonly supabase: Supabase,
  ) {
    console.log('debug-initial', supabase);
  }

And how can I inject a service into MessageHandler, something I wanna ask is:

@Injectable()
export class MessageHandler {
  constructor(private readonly subapase: Supabase) {}

  @SqsMessageHandler(awsConfig.name, false)
  async handleMessage(message: AWS.SQS.Message) {
   // call an service something like that
    // DatabaseService.storeMessage(message)
  }
}
